Homework Statement
When a jet plane flies overhead at a high altitude, the sound from the engines can be heard, but the sound seems to come from well behind the aircraft. If you knew the altitude of the jet to be 10,000m, how could you estimate the speed of it? Show this using an example.
Homework Equations
c = 3.00*10^8m/s?
The Attempt at a Solution
I asked my teacher this question, but he told me to think about it. He hinted at using the speed of light, speed of sound, and a stop watch. I tried drawing a diagram showing how the person would see the plane first before hearing the engine. I know sound travels slower than light, but I don't know what to do next.
